The BBC has released the first photo of Peter Capaldi on the set of Doctor Who. This is his first full day of filming. I've also included the eleventh Doctor's regeneration from the Christmas Special, which is Capaldi's first appearance as the twelfth Doctor.
We still have yet to see Capaldi in his own unique Doctor clothing style, as he is still wearing Matt Smith's clothes that he regenerated in. It will be interesting to see what style his Doctor will ultimately take.
